Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25554, here are decompositions:
- 13 + 25541 = 25554
- 17 + 25537 = 25554
- 31 + 25523 = 25554
- 83 + 25471 = 25554
- 97 + 25457 = 25554
- 101 + 25453 = 25554
- 107 + 25447 = 25554
- 131 + 25423 = 25554
Showing the first eight; more decompositions exist.
